Kevlar is a synthetic fibre used mainly for which protective applications?

• A. Body armour and PPE garments.
• B. Electrical insulation for cables.
• C. Water filtration membranes.
• D. Wood finishing products.

Answer: (A)

Kevlar’s standout property is its very high tensile strength and ability to absorb a lot of energy per unit weight. When woven into fabrics and layered, these fibres spread the impact across many fibres, so a fast-moving object loses energy gradually rather than causing a single break. This means protective gear can be lightweight yet capable of stopping or slowing bullets and blades, which is essential for body armour and PPE garments. The other options rely on properties Kevlar isn’t primarily used for—electrical insulation needs materials with specific dielectric performance, membranes require porous, permeable structures for filtration, and wood finishes need coatings for appearance and protection. So the best use is in body armour and PPE garments.
